To aZZ'whO/m it mag concern."

Be it known that'l, JOHN PETERSON, a citizen of the United States,residing at Saratoga Springs, in the county'of Saratoga and State of NewYork, have invented .new and useful Improvements in Irrigating Devices,of which the fica'tion. r

This invention relates to irrigating, devices of that type which areknown as sprinklers.

The prime object of the invention is to simplify and improve theconstruction of following is a specithe nozzle or outlet and the mannerof connecting the'same with the supply pipe.

A'- further object of, the invention is to produce a sprinkler nozzlewhich to a large extent will operate as a strainer to excludeobstructions whereby the bore of the nozzle might become clogged. Y a

A further object of the invention is to produce a sprinkler nozzle whichmay be easily and thoroughly cleansed by flushing the supply pipe withwhich it is connected.

A further object of the invention is to simplify and improve theconstruction and arrangement of the supply pipe and t6 pro duce inconnection therewith a primary strainer whereby obstructions of a coarsenature will be preventedfrom reaching the sprinkler nozzles.

With these and other ends in view which will readily appear as thenature of the invention is better understood, the same convin accordancewith the invention.

sists in the improved construction and novel arrangement and combinationof parts which will be hereinafter fully described and particularlypointed out in the claims.

In the accompanying drawing has been illustrated a simple and preferredform of the invention, it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications' within thescope of theclaims may be resorted to when desired.

Corresponding parts in the several figures are denoted by likecharacters of reference.

Theirrigating stand A, which may be of many different forms, has in thedrawing been shown as comprising a pipe having downturned ends 16-whichare connected by T-couplings 17 with horizontally disposed foot pipes 18and 19 which are intended and adapted to rest on the ground, therebysupporting the pipe 15 in" an approximately horizontal position and atan elevation which is determined by the dimensions of the downturnedportions 16.

The foot pipe 18 is obstructed at one end by a cap 20. The other end ofsaid foot pipe carries a cylindrical casing 21 containing a diagonallydisposed strainer 22, said strainer casing being in turn connected withthe source of supply by means of a hose 23 or in any other convenientmanner. The foot pipe 19 is terminally obstructed by detachable caps 24.

The main pipe 15, as well as the pipes 18,

the form of nozzle shownin bore 27 and being provided at the endsthereof with slits or kerfs'28 which may be of a width approximatelyequal to the diameter of the bore, each of said kerfs producing twospaced lugs 29. By bending or pressing said lugs in the direction ofeach other without causing them to impinge on each other, narrow slits30 will be produced at the ends of the body in spaced relation to theends of the bore, and by so bending the lugs, it will also be seen thatthe ends of the nozzle will become slightly tapered externally, asclearly seen in Fig. 6. The nozzles are to be made of a diameter equalto or very slightly exceeding the internal diameter of the apertures 25,so that by in- L ment, causing it to be held or retained in position byfrictional engagement with the.

walls of the aperture. The pipes 15,18 and 19 may be ordinary iron pipeswith walls of a thickness materially less than the length of thenozzles, so that the nozzles when applied will project partly within andpartly outside of the pipes, as will be very clearly seen in Figs. 3 and9 of the drawing.

Under the modified construction of the nozzle shown in Figs. 7, Sand 9,one end of the same is cut off obliquely, as seen at 32, prior to theformation at this end of the kerf or slit, which is here designated by33. It follows that when the terminal lugs, here designated by 34, arebent in the direction .of each other, an inclined slit will be producedwhich is of greater length than would otherwise be the case, therebyfacilitating the admission of water to the bore 27 and. also increasingthe straining area. When water is turned'nto the irrigating stand itwill find its way through the nozzles which, as seen in the drawing, maybe faced or pointed in various directions. The compressed lugs at theouter ends of the nozzles will spread the water in the form of a finespray closely imitating a gentle rain.

It is obvious that the irrigating stand may be readily moved fromplace'to place,

as required. Should the nozzles become obstructed, the caps 20 and 24may be removed, after which by turning water through the pipes underpressure the said pipeswill be flushed and obstructions removed from theinner ends of the nozzles.

It will be readily seen that the shape and formation of the irrigatingstand may be greatly varied without departing from the spirit and scopeof the invention. The strainer casing 21 may be dispensed with whendesired. It may be also stated that the slit or kerf producing the wingsor lugs at the outer or discharge end of the strainer nozzle may bedispensed with when pre- 'ferred.

At the inner end of the strainer nozzle the kerf or slit producing thewings or lugs is 1 highly essential as well as the subsequent bending ofthe wings or lugs in the direction of each other to produce a taperingformation of the end ortion of the nozzle. This is partly in or er thata narrow slit may be formed through which water may pass, while sedimentand dirt will be excluded from the bore of the nozzle, thus producing adistinct strainer action. This formation is also highly desirable,inasmuch as the tapered end of the nozzle may be readily inserted intoone of the apertures of the irrigating pipe and secured there by asimple tap with a hammer or other tool. The apertures in the irrigatingpipe need not be tapered or otherwise specially formed for the receptionof the nozzle. The nozzle itself is also free from external threads orfrom any special structural feature for connection with the irrigatingpipe.

Having thus described the invention, what is claimed as new is 1. Acombined sprinkler. nozzle and strainer consisting of a cylindrical bodyhaving a longitudinal boreand provided at its intake end with a terminalslit producing spaced lugs, said lugs being bent toward each other toproduce -an intake opening of less width than the diameter of the borefrom which obstructions will thus be excluded.

2. The combination with an irrigating pipe having an aperture in thewall thereof, of a sprinkler nozzle consisting of a cylindrical bodyhaving a longitudinal bore and provided at its intake end with aterminal slit producing spaced lugs which are bent toward each otherproducing an external beveled portion which may be frictionally engagedin the aperture and producing also an intake opening of a width lessthan that of the longitudinal bore from which obstructions will thus beexcluded.

3. A combined strainer and sprinkler nozzle consisting of a cylindricalbody having a longitudinal bore and provided at each end with a terminalslitproducing spaced lugs which are bent toward each other to formintake and exitopenings of less Width than the diameter of the bore.

4. The combination with an irrigating pipe, the wall of which isprovided with a cylindrical aperture, of a strainer nozzle consisting ofa cylindrical body having a longitudinal bore and rovided at its intakeend with a terminal sit producing spaced lugs which are bent toward eachother to produce an external beveled portion for fric- ,tionalengagement in the aperture.
